Nano board LEDs are flashing sketch not working


I'm using a Nano *328 which has been working fine until now!

I'm trying to control a servo & uploaded the sample code (Sweep) from the Arduino site.

It looked like it uploaded fine but when I power every up all I get are the blue LED and the other 3 LEDs flashing in sequence.

I'm guessing this means something but cant find any reference to what it means.

EDIT: This only happens if the servo is connected to the PWM output on pin 9, otherwise the LEDs arent lit.

Any help appreciated.
